The digital image methods which are used to process interferograms are introduced, especially the Hilditch thinning algorithm is discussed.

Based on the noise in the complex interferograms satisfying an additive noise model,a noise reduction scheme using wavelet packet soft thresholding method to respectively remove the noise in the real and imaginary part of the complex interferograms is proposed.

This paper elaborates how to apply genetic algorithms to calculate the binarization threshold value of the moire image.

In order to align the distortion caused by the jitter of push-broom flat,the Fourier-Mellin algorithm is proposed to recover the interference image of a large aperture static interference imaging spectrometer.

Secondly based on requirement of interference image, the interference image processing system is developed by the mixing programme with VB and MATLAB, which has many the features such as compact structure, reliability, various functions, friendly interface and easy use.

Results and Conclusion\ The number of beams is increasing in geometric series when the light propagates in the two layer system, and it is necessary for study of the interference pattern of the system and for further .

Young’s two slits interference of discrete double light source is numerically simulated,and the curve of visibility, curve of light distribution and interference pattern are solved with different type of line and line width.

Young experiment of discrete double-lined spectrum is simulated by the way of Matlab in order to study how the type or width affects interference pattern.
